This amount does not really bother me too much. You find it all the time in slabbed coins, often much worse than this. That being said, I would still give it an acetone bath and maybe toothpick treatment in the problem areas.

Verdigris is a chemical reaction.
It will continue unless you change the conditions around the coin.
And acetone won't help much removing verdigris.
Get that removing stuff (verd-i-care?)

Avoid the verdi. Why ? Nothing wrong with verdicare, it was developed by one of our CCF members and it works. |

Oh that's very minor. I would use my VC and not give it a second thought.

my answer depends on the year of this coin, is it a more rare coin with few high grade examples? or is this a 1907 that is half the price because of the verdigris?

That little bit is nothing. Hit it with VC and there ya go.
peter, were you saying avoid verdigris, or avoid verdi care? Not really clear there.

I used that VerdiCare stuff on over 30 Indian heads so far with a toothpick and it works pretty good ones with worse then this.

I developed a new copper coin cleaner in the lab that is 10X better than the original Coin Care or Vedi-Care. Contact me privately if interested - it has worked pretty well on green oxidation build-up areas assuming its just on the surface and not to deep into the coin's surface. It will not change to copper coin's surface color. Acetone dries out a coin's surface leaving it White, Xylol is good put not as good as side by side testing with JPL Coin Care. Its $30 for a 2 oz. bottle. This includes P&H. After 60 customers - no negative reports. The only patina change is when you remove 200 year old soil the coin will have cleaner look but no metal change occurs in terms of color and appearance.

I called my product JPL Coin Care. It was developed by myself - I sell it privately - most experienced copper collectors will tell you acetone dries out a coin's surface and at times leaves a mild white film which is why xylol is more of the GO TO material. After my Originial COIN CARE was expired I developed this product. I have mostly been selling it to experienced collectors of the C4/EAC organization.
I agree with the statement - "Nothing can really clean copper effectively." Until my product came out <BG>.
I am Chemist and have developed industrial cleaners ... there are other factors but these are private ... contact me privately. After 55 sales no one has requested there money back yet ... <BG>.

Verdicare is very established and has a large following here on the forums. I think if you want folks to take you seriously, you should provide some before and after photos of coins that you have used it on....and maybe some comparisons of how verdicare works on similar coins. |
